Detailed description of the invention
See Fig. 1-3, the implementation case comprises controlling organization, selects pearl bar 1, and in order to simplify pearl drives structure, select pearl bar 1 to adopt suspension, pearl can rely on gravity slippage.Select pearl bar 1 to comprise for the thin diameter section 11 of beading and the wide section 12 for screening pearl internal diameter, wide section 12 also replaces by particle size screening point.For preferred wide section 12 in the implementation case.Select pearl bar 1 thin diameter section 11 for beading, thin diameter section 11 screens with wide section 12 or particle size and is a little connected, select junction, pearl bar 1 thickness footpath to be provided with one and smash internal diameter does not screen the pearl of point Sui Zhu mechanism 2 by wide section or particle size, select pearl bar 1 to be provided with to detect pearl by or the pearl testing agency that stagnates in wide section 12 screening place, control device receives testing agency's Detection Information and control Sui Zhu mechanism stagnates accordingly or broken pearl action.
Testing agency comprises one or more first detector 31, be arranged at wide section 12, the junction, thickness footpath of thin diameter section 11 or its above; Or be arranged at particle size screening point place or particle size screening point top.Sui Zhu mechanism 2 can be clamping claw 21 or hammer 22, and clamping claw 21 or hammer 22 are by motor, air pressure or hydraulic-driven.
In order to ensure to select pearl coherent, continue and automation, also comprise a beading mechanism 4, beading mechanism 4 can select the oscillatory type stringing machine on existing market directly to screen loose pearl, or other or manual beading continuously.Pearl bar 1 thin diameter section 11 beading one end is selected to be connected with beading mechanism 4 output.Testing agency also comprises one or more and is arranged at the second detector 32 selecting and detect pearl above pearl bar 1 thin diameter section 11 or thin diameter section 11, and controlling organization receives the second detector 32 information and controls beading mechanism 4 and starts or stops accordingly.So both ensure that the continuity selecting pearl bar 1 thin diameter section 11 to supply pearl, and can prevent from again selecting the too much overfill of pearl on pearl bar 1 simultaneously, avoid beading mechanism 4 to supply the too much overfill of pearl, affect the stability of beading bar 1 thin diameter section 11, prevent from selecting pearl bar 1 to shake.
Thin diameter section 11 be provided with driving wheel 5 one or more, to ensure that the pearl on thin diameter section 11 has enough driving forces, the screening point combined by thickness footpath smoothly, pearl bar 1 thin diameter section 11 is selected to detour on a driving wheel 5 or between multiple driving wheel 5, specifically can on the one or more driving wheel of spiral winding, or to detour in S and between multiple driving wheel 5.Be a driving wheel 5 in the implementation case accompanying drawing, thin diameter section 11 is helically wound around on driving wheel 5, ensures the stability selecting pearl bar 1.Certain wide section 12 also can arrange driving wheel 5.
In pearl screening process, due to wide section 12 or pearl endoporus clean not smooth, pearl is surprisingly stuck on wide section 12, pearl is caused to be accumulate to screening place of thickness footpath combination, first detector 31 will be reported by mistake, and photos and sending messages is to control device, to such an extent as to the pearl at continuous uninterrupted mistakenly hit this screening point place broken of Sui Zhu mechanism 2, therefore as optimizing, testing agency also comprises the 3rd detector 33 being arranged at and selecting on pearl bar 1 wide section 12 or under particle size screening point.
Wherein, first, second, third detector 31,32,33 is all preferably one, and one can be detected the pearl selecting a some position on pearl bar 1, by this detection signal sustained delivery corresponding time as separation, realizes the switching of corresponding control information.And multiple detector can be used to detect the one section of pearl selected on pearl bar 1, the upper and lower test point of one section of pearl realizes the switching of corresponding control information as the separation switching the different information of transmission.
First, second, third detector 31,32,33 comprises presses close to select pearl bar 1 monitor the stroke device 34 of pearl and detect the stroke inductor 35 of stroke device 34 location status.As preferably, detector can comprise pressing close to the runner 36 of stroke device 34 contact, pearl bar 1 is selected to be held between stroke device 34 contact and runner 36, circumferentially being provided with of runner 36 one or both ends can the projection 37 of jack-up stroke device 34 contact, projection 37 is provided with gap with pearl in the axial direction, not affect the activity of pearl.Projection 37 can make the regular swing of stroke device 34, prevents stroke device 34 slow in reacting because of unexpected situation bonding.Stroke device 34 can be detect the resetted slide block of position signalling maybe can to reset fork, for fork in the implementation case, stroke device 34 comprise one can reset fork 34a, be arranged at the protruding 36a of arcuation that fork 34a coordinates with runner 36 as contact, fork 34a end is provided with the convex tail 34b coordinated with inductor 35.So that detection pearl sensitive more accurately.
Below in conjunction with the use of present device, explain the inventive method further.
Start and select pearl equipment, beading mechanism 4 is started beading and is delivered to the beading one end of the thin diameter section 11 selecting pearl bar 1 by output, continue conveying and form pearl string, first the pearl of movement can stir the fork 34a of the stroke device 34 of the second detector 32, make its swing that is continuous or interval, stroke inductor 35 is by this signal transmission of detecting to control device, and this kind of signal is preset as the signal that controlling organization judges the normal work of beading mechanism 4.If the pearl accumulation bunchiness on thin diameter section 11, and highly exceed the detection location point of the second detector 32 above thin diameter section 11, the pearl string then formed continues the fork 34a backing down stroke device 34, stroke inductor 35 continues corresponding a period of time and transmits this kind of signal, then control device judges not need beading, beading mechanism 4 beading will be suspended, until the pearl string on thin diameter section 11 is consumed to the detection location point lower than the second detector 32.Treat the stroke device 34 fork 34a of the second detector 32 continue or only on runner 36 the protruding 36a of arcuation driving under do regular swing, stroke inductor 35 transmits this kind of signal, then control device judges to need beading, starts beading mechanism 4 and continues beading until pearl accumulation is again more than the position of the second inductor 34.
Pearl is carried descending further, and can be delivered to the screening of junction, thickness footpath in conjunction with driving wheel 5, the pearl that internal orifice dimension meets the demands then continues to come downwards to discharge by junction, thickness footpath and selects pearl bar 1.The underproof pearl of internal orifice dimension then can be stagnated in junction, thickness footpath, and follow-up pearl then can be forced to stagnate accumulation.The Cleaning Principle of the first detector 31 can with the principle of the second detector 32, i.e. normal signal, Sui Zhu mechanism 2 does not work.When the fork 34a of the stroke device 34 of the first detector 31 continues to be backed down a period of time, the stroke inductor 35 of this detector 31, by this signal transmission to control device, control device then judges that the underproof pearl of internal orifice dimension is stagnated in junction, thickness footpath, and drives Sui Zhu mechanism 2 action to smash this underproof pearl.Follow-up pearl will continue through screening point, waits to be screened, filters out the pearl that internal orifice dimension is qualified.
3rd detector 33 Cleaning Principle is with first, second detector concept.During work, namely when the pearl on wide section 12 wears place, the 3rd detector 33 regular event normal through wide section, control device judges do not have pearl to be trapped on wide section 12.Shelves the 3rd detector 33 does not detect that wide section 12 corresponding position has pearl to block stop, and when only having the first detector 31 the screening point of pearl not by junction, thickness footpath to be detected, control device just can drive Sui Zhu mechanism 2 to smash the real underproof pearl of internal orifice dimension; Otherwise the first, the 3rd detector 31,33 detects respectively and selects pearl bar 1 corresponding position to have pearl to stagnate, and controlling organization then can not drive Sui Zhu mechanism 2 mistakenly hit to sieve broken reconnaissance pearl, until the pearl on wide section 12 normally passes beading bar.
